A word used to describe a tribe, family, or individual with the personality of an asshole. Not necessarily making them assholes, but having the qualities of one. Will often poke fun at you or your friends in good humor. Every moment serves as an opportunity to crack a joke and sarcasm is the first language of a Romero.

Dude, that guy called me a faggot!
It's okay, he's a Romero. He meant no harm by it.
